# Prepares the bubble.jar file for active usage.
#
# 1. Copy scripts to bubble-server/target/classes/scripts
#
# 2. If the environment variable INSTALL_WEB is equal to "web", also build and install the bubble-web
#    site to bubble-server/target/classes/site
#
# Usage:
#
#   prep_bubble_jar
#
# Environment variables:
#
#   INSTALL_WEB       : if this is equal to 'web' then the frontend will be built and included in the jar
#   DEBUG_BUILD       : if this is equal to 'debug' then nothing will be done, the jar will be left as-is
#   BUBBLE_PRODUCTION : if this is set to anything, then a production build will be made.
